Wujek Coal Mine

Wujek Coal Mine is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Wujek Coal Mine rather than just read about it. In short: Wujek Coal Mine (Polish: Kopalnia Wujek, full name in Polish: Kopalnia Węgla Kamiennego „Wujek”; German: Oheim) is a coal mine in Katowice, Poland. It is widely known in Poland as the place of the massacre of striking miners in 1981 (most often referred to by the euphemism 'Pacification'), as well as being the site of a deadly mining accident in 2009.

Key takeaways

Wujek Coal Mine belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Wujek Coal Mine to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Wujek Coal Mine from memory before moving on to harder problems.

Reference excerpt

Wujek Coal Mine (Polish: Kopalnia Wujek, full name in Polish: Kopalnia Węgla Kamiennego „Wujek”; German: Oheim) is a coal mine in Katowice, Poland. It is widely known in Poland as the place of the massacre of striking miners in 1981 (most often referred to by the euphemism 'Pacification'), as well as being the site of a deadly mining accident in 2009. Mining operations began in the vicinity as early as the 16th century. The present mine, Oheim, was established in 1899 by a merger of six mining operations existing in Silesia (then a part of Germany). The peak Polish production was in 1979 (3.88 million tons that year). Currently, the Wujek mine produces sub-bituminous coal with a typical energy content of 30000-35000 kJ/kg, volatile content of 30-31%, ash content of less than 5%, and sulfur content of less than 0.6%. On 1 April 2017, the Wujek mine was taken over by Polska Grupa Górnicza (pl), and in 2021, it was connected to the Murcki-Staszic Coal Mine (pl:Kopalnia Węgla Kamiennego „Murcki-Staszic”) via an underground passageway. Since then, both formerly independent mines are now operated as a single entity called Staszic-Wujek Coal Mine (pl:Kopalnia Węgla Kamiennego „Staszic-Wujek”). The name "Wujek" means "Uncle" in Polish.

Worked examples

Example 1 — a first encounter with Wujek Coal Mine

Start with the simplest possible case. Write down what Wujek Coal Mine claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Wujek Coal Mine before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Wujek Coal Mine ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Wujek Coal Mine

In research: Wujek Coal Mine appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Wujek Coal Mine in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Wujek Coal Mine is common in secondary-school and first-year university syllabi. It links to neighbouring topics Coal mines in Silesian Voivodeship, Mine stubs, Poland geography stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Wujek Coal Mine outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
